LUBRICATING APPARATUS,

SPECIFICATION forming part of Letters Patent No. 302,704, dated July 29` 1884.

. U Application filed May 15, 1884. (No model.)

To all whom, t may concern,

Be it known that I, JOHN LIsrnR BOOTH, acitizen ofthe United States, residing at Gedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Lubricating Apparatus; and I do hereby declare the following to be a sufiieiently full, clear, and exact description thereof to enable others skilled in the art to make and use the said invention.

This invention relates to that class of lubrieators which deliver oil slowly in adjustable quantities to machinery in motion, and has for its object the more certain and uniform delivery of oil without waste and, while in operation, .permitting` ready inspection and as-` certainment of the quantity, frequency, and color of the oil as it is fed to the machinery, and a washing or filtering of the oil through a column of water.

rIhe nature of this invention consists in a vessel having a removable cover and a vent therein, and means of closing such cover and vent, an inverted siphon leading from the bottom of said vessel, the rising limb of which siphon is transparent, and from the upper end of which transparenttube a tube provided with a stop-cock or valve or` other equivalent means ot' constructing and stopping the V[low of duid from the siphon to the bearing.

I will now proceed to fully and particularly describe the mode of making and using this invention, referring in so doing to the drawing annexed and the letters of reference marked thereon.

The drawing shows a vertical central section of this invention.

A represents a cylindric vessel provided with a screw cap or plug, B, fitting tightly upon the rim of the vessel A when screwed down, and when raised slightly opens an airvent, B, leading through the screw-thread to the cavity B'l in the cap or plug B. The vent B should be in duid communication with the place into which the oil is to be delivered, so as to produce the saine pressure upon the surface of the oil in the cup A as the oil meets on its delivery from the cock E.

In case the oil is applied in a cylinder, steam or valve chest, or in a vessel or space not under atniiospheric pressure, a tube, B3, provided with a valve or cock, Bi, is `used to connect it with such chamber, and the cap B is kept closed upon the vessel A.

Leading from the bottom of the vessel A is an inverted siphon, D, the descending limb D' ot' which may be either of metal or glass, for purposes of strength, metal being preferable. rIhe rising limb D2 of this siphon is larger than the limb D', and is transparent, and from the upper end of the rising tube D'l a passage, D3, leads horizontally to a stopcoek, E, by which the iiow oioil outward may be regulated.

For purposes of convenientapplication to machines, the passage D3 may lead through a descending tube, D", and terminate in a cock, E', as indicated in the dotted portion of` the ligure.

The invention is used in the following manner: The cap B is removed and the cock E opened. TWater is then poured in until the inverted siphon I) is iilled, after which the cock E is closed and oil placed in the cup A. The cover B is then replaced, and when the oil 1s to be applied to lubricate'the machinery upon which the cup is to be used the cap Bis unserewed far enough to open the air-vent B, and the cock E cautiously opened until the desired quantity of oil Hows therefrom. The oil passes in globules through the water in the glass tube D2. and the frequency, color, and size of the globules are readily ascertained.

Then it is desired to stop the flow of oil from the apparatus, the cap B is screwed down, so as to close the air-vent B, and the cock E remains in proper adjustment without requiring attention or regulation.

Having described my said invention, what I claim is- A lubricating-eu p consisting of a vessel having a cover provided with an air-vent and au inverted siphon adapted to contain water, leading from the bottom of said vessel, and having a transparent rising limb of larger caliber than the descending limb, and provided at its outlet with a valve or cock for adjusting and regulating the flow oi` lubricating-fluid, substantially as set forth.

JOHN LISTER BOOTH.
